The U.S. is planning to muck around with one of Canada’s most treasured landmarks.

The New York State parks system is putting forward an idea to “dewater” the American side of the falls. In other words–yes–they’re going to turn it off like a faucet.

The reason behind this insane-sounding idea is that the U.S. wants the replace two 115-year-old stone arch bridges that are used to access Goat Island. The good news, however, is that the shutdown will be temporary, and won’t affect our much-more-awesome Horseshoe Falls (after all, who really goes to Niagara to look at the American falls?).

Nothing is set in stone just yet though. Three different versions of the plan will be presented on Jan. 26, with two of them calling for a temporary shutdown of the attraction. If passed, the falls would only be dry for between three and nine months.

So where will all the extra water go? Currently, about 85 per cent of the Niagara River flows over the Canadian falls anyway, so the Americans plan on simply diverting the rest to our side of the border. This isn’t actually the first time Niagara has been dried out, either. The U.S. did it once in 1969 to study the effects of erosion. Interestingly, a lot of tourists actually came out to see what was lying under the falls when that happened.

The answer? Two bodies and a lot of coins.

So tread lightly, America. One wrong move and we might decide to “dewater” your half of the Great Lakes.
